The real cost of owning a superyacht

$400,000 in fuel, $350,000 for docking and $1.4m in wages PER YEAR: Infographic reveals the real cost of owning a superyacht

Superyachts are generally owned by Ultra High Net Worth Individuals

Insurance company Towergate calculates what they really pay

On average, owners pay 10 per cent of yacht's value in costs per year

From Russian oligarchs to Middle Eastern royalty to Hollywood producers, it takes a certain type of person to own a superyacht - crucially, they must be super rich.

The official term for this fortunate minority is a Ultra High Net Worth Individual, someone with more than US$30million (£20m) in net assets, and there are just 200,000 of them in the world.

But even for the likes of Roman Abramovich and UAE president Khalifa Al Nahyan, owners of two of the costliest private vessels in the world, the costs associated with keeping such a big boat on the water would have them double-checking their direct debits.

Insurance company Towergate has compiled a study to find out the real cost of owning a superyacht and the figures are, for us mere mortals, almost inconceivable.
